Description

<p>Cardiac tumors are rare, and if malignant, the prognosis is often poor. Specific complications occur depending on the site, and pulmonary tumor embolism is most fatal when the tumor site is in the right heart. Although, surgical intervention does not necessarily improve the prognosis of the tumor itself or survival, surgery can prevent sudden death and improve heart failure symptoms, which in turn is expected to improve the activities of daily living (ADL) and maintain the quality of life (QOL) by allowing hospital discharge. In cases of metastatic tumors or tumors due to progression of liver or kidney cancer, resection of the tumor not only improves ADL and QOL but may also prolong survival and improve prognosis. This study presents five cases of right cardiac malignant tumors in which surgical intervention using cardiopulmonary bypass was performed. In two cases, the patients died early but in the remaining three, relatively longer survival was observed. The patients were discharged and returned home but died later. Postoperative adjuvant chemotherapy may be effective in such cases depending on the tumor morphology. We conclude that surgical intervention was able to prevent sudden death, and a diagnosis followed by adjuvant chemotherapy might extend the survival. On the other hand, early postoperative lung and pulmonary circulatory disorders may be at risk of progressing to DIC and MOF and impairing survival.</p>
